具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
图1示出了本申请实施例提供的基于服务的网络架构的示意性框图。该网络架构以服务为基础,得到多种不同类型的网络功能模块,网络功能模块之间通过服务化接口以网络功能服务调用的方式进行交互。
应理解,本申请实施例中的网络功能模块具有特定功能和网络接口,可以是专用硬件上的网元,也可以是专用硬件上运行的软件实例,还可以是相关平台(如云基础设施上)上的虚拟功能实例,本申请实施例对此不作限定。
下面将结合图1对该基于服务的网络架构中的各个模块进行介绍:
无线接入网络(radio access network,RAN)模块102:负责用户设备(user equipment,UE)101的接入。可以理解的是,在实际表述过程中,RAN也可以简写为AN。
可选地,本申请实施例中的UE可以是移动的或固定的,该UE可以指接入终端、终端设备、移动终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来的第五代(5th generation,5G)系统或新无线(new radio,NR)系统中的用户设备。
访问与移动性管理功能(access and mobility management function,AMF)模块103:负责与现有的移动管理实体(mobile management entity,MME)中的移动性管理类似的功能,用于控制UE对网络资源的访问和对UE的移动进行管理。AMF模块103与RAN模块102互相通信,以对接入网控制面进行处理,其中,N2不是服务化接口。
鉴权服务功能(authentication server function,AUSF)模块104:负责密钥的生成,以及与UE 101之间的双向鉴权。
会话管理功能(session management function,SMF)模块105:负责管理UE的会话,包括会话的建立、修改和释放。
网络开放功能(network exposure function,NEF)模块106:负责将核心网内的网络功能服务安全地提供给外部网络实体服务,以及内外网信息转换等。
网络功能数据库功能(NF repository function,NRF)模块107:负责服务发现等功能。
策略管控功能(policy control function,PCF)模块108:负责管理网络行为的统一策略框架;提供策略规则给控制平面执行等功能。
统一数据管理(unified data management,UDM)模块109:包括前端(front end,FE)和用户数据库(user data repository,UDR)。其中,FE负责信用评级处理、位置管理、订阅管理等功能,并可以访问存储在UDR中的用户订阅数据,UDR是一个用户订阅数据存储服务器,负责向前端提供用户订阅数据。
应用功能(application function,AF)模块110:提供应用服务。
如图1中所示,AMF模块103具有服务化接口NAMF、SMF模块105具有服务化接口NSMF、AUSF模块104具有服务化接口NAUSF、NEF模块106具有服务化接口NNEF、NRF模块107具有服务化接口NNRF、PCF模块108具有服务化接口NPCF、UDM模块109具有服务化接口NUDM、AF模块110具有服务化接口NAF。
应理解,本申请实施例中的各个网络功能模块的服务化接口的还可以为其它名称,本 申请实施例对此不作限定。
在基于服务的网络架构中,各个网络功能模块之间通过服务化接口调用网络功能服务,由于全网的服务化接口支持统一的通信协议,这就意味着,一个具备服务化接口的网络功能模块能够被任意一个具有服务化接口的其他网络功能模块访问,即一个具备服务化接口的网络功能模块提供的网络功能服务能够被任意一个具有服务化接口的其它网络功能模块调用。这样以来,在基于服务的网络架构中可能会产生网络功能服务滥用的问题,安全性能较差。
例如,传统的网络架构中,AF与UDM之间无通信接口,即AF不能直接访问UDM,但是在基于服务的网络架构中,AF具备调用UDM中的网络功能服务的能力,由于UDM中存储有与用户相关的敏感信息,AF能够通过服务化接口任意调用UDM中的网络功能服务,有可能导致用户信息的泄露。
本申请实施例提供的用于调用网络功能服务的方法,能够提高调用网络功能服务的安全性。
